Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application incorporates by reference, and claims
priority to and the benefit of, German patent application serial
number 102005014709.7, which was filed on Mar. 31, 2005, the entire
disclosure of which is hereby incorporated herein by reference.
TECHNICAL FIELD
[0002] The present invention relates to a shoe for receiving a
housing of an electronic assembly and to a housing for receiving an
electronic assembly.
BACKGROUND
[0003] Professional athletes, as well as amateurs, desire in an
increasing number of sports to electronically keep track of their
athletic performance. For example, electronic speedometers with a
plurality of functions are nowadays standard equipment for every
ambitious race or mountain biker. Small computers are also used for
running to count the number of steps, the speed, and thus the
covered distance, and can provide additional information.
[0004] Whereas it is comparatively easy to mount a computer to a
bicycle, there exists a problem in the case of running. On the one
hand, the computer should somehow be connected to the shoe in order
to reliably detect the steps of the athlete using, for example, a
contact sensor, a shock sensor, or an accelerometer in the shoe
sole. On the other hand, the computer must be protected against
humidity and mechanical damage. Further, the computer should be
easily accessible to view the recorded data and to perform inputs,
if desired, or to connect the computer to a PC for further
evaluating the measured data.
[0005] A similar problem occurs if a runner intends to carry other
types of computers, such as, for example, a MP3 player. Although it
is generally possible to attach such an electronic assembly to the
body using a strap or the like, such an attachment can be
uncomfortable and impede movement of the wearer during a high
performance activity.
[0006] There are many approaches known from the prior art as to how
to attach computers to a shoe. For example, U.S. Pat. Nos.
6,536,139 and 6,278,378 and Japanese Publication No. 60 200120, the
entire disclosures of which are hereby incorporated herein by
reference, disclose arrangements where the computer is attached to
the laces or the tongue of the shoe. A modification of this design
is disclosed in U.S. Pat. Nos. 4,649,552 and 6,183,425, Japanese
Publication No. 60 84689, and PCT Publication No. WO 88/04768, the
entire disclosures of which are hereby incorporated herein by
reference, where a sensor is integrated into the sole region. The
computer, which processes the signals of the sensor to provide
useful data, is again arranged in the region of the laces and/or on
the instep. U.S. Pat. No. 4,771,394, the entire disclosure of which
is hereby incorporated herein by reference, discloses a system
where the computer is attached to the heel of the shoe.
[0007] All of these arrangements of a computer on a shoe have,
however, the disadvantage that the sensitive electronic components
of the computer are protected insufficiently against damage. When
the runner stumbles or falls, there is a significant risk that the
housing of the computer, which is typically made from plastic
materials, is subjected to mechanical loads that it can not
withstand. Protective coatings, which can be effective, are
excluded, since the electronic assembly would reach a size and
weight impairing performance of the wearer when the electronic
assembly is arranged on the outside of the shoe.
[0008] There is, therefore, a need for a shoe that can securely
receive an electronic assembly, such as an electronic pedometer, an
accelerometer, or a speed sensor, and that overcomes the above
discussed disadvantages of the prior art. Furthermore, there is a
need for a housing that can securely retain an electronic assembly
on a shoe, such that the electronic assembly is permanently
protected against damage.
SUMMARY OF THE INVENTION
[0009] The problem is solved, in part, by releasably integrating
not only a sensor, but a complete electronic assembly, such as a
pedometer, an accelerometer, a speed sensor, a MP3 player, or any
arbitrary electronic assembly into the shoe sole. Using a cable or
a wireless transmission, an additional user interface may be
connected to the electronic assembly to allow inputs or the reading
of measured data even during operation.
[0010] The present invention is based on the realization that the
required circuits for electronic assemblies have become smaller and
can, therefore, be easily arranged in a recess of the sole of a
shoe without significantly affecting the functional properties of
the sole (e.g., cushioning and support). At the same time, the
electronic assembly is completely enclosed and, therefore,
perfectly protected against mechanical impacts. An arrangement in a
recess of the sole is also aesthetically pleasing, since the
housing of the electronic assembly can not be recognized from the
outside.
[0011] Since the housing is not permanently integrated into the
sole, but only releasably arranged in the recess, it is always
possible to replace the housing to, for example, exchange a faulty
electronic assembly, exchange the battery, or remove the housing
and its electronic assembly from the recess so that it can be
connected to a PC or the like for a further evaluation of the
data.
[0012] The detachable arrangement of the housing also makes the
replacement of one electronic assembly for another electronic
assembly having a different functionality easy. A unit for
detection of a running movement by counting steps or measuring
accelerations can thus be exchanged directly against another
assembly, for example, a GPS receiver for position determination, a
pulse sensor, or other electronic function units. The
exchangeability is particularly desirable in the context of an
intelligent shoe, where the cushioning properties of the sole can
be changed under the control of an electronic control unit. If this
control unit is defective, needs to be provided with new firmware,
or needs to be exchanged for a more recent model, a mounting
arrangement in accordance with the invention can be used in a
particularly effective manner. It is also possible for the assembly
to be removed in order to exchange, read, expand, etc., the memory
of the electronic assembly.
[0013] In one aspect, the invention relates to an article of
footwear having an upper and a sole unit attached to the upper. The
upper forms a cavity for receiving a wearer's foot. The sole unit
includes a recess for releasably receiving a housing of an
electronic assembly. The recess is at least partially accessible
through the cavity of the upper. The upper can be essentially any
conventional upper for receiving a wearer's foot, including straps
or other structure for surrounding the wearer's foot. In one
embodiment, the sole unit includes a tub-like structure for forming
the recess.
[0014] In various embodiments, the article of footwear includes the
housing and the electronic assembly disposed therein. The
electronic assembly can be a pedometer, a shock sensor, a global
positioning system, a pulse sensor, an accelerometer, a speed
sensor, an MP3 player, or combinations thereof. The recess can be
arranged in a region of the sole unit corresponding to a wearer's
midfoot region. Thus, the housing is arranged in a region of the
sole that is subjected to the smallest ground reaction forces and,
accordingly, subjected to the smallest deformations.
[0015] The sole unit can include an opening or window adapted to
permit a wearer to inspect and/or operate the electronic assembly.
An additional user interface can also be provided on the shoe. In
one embodiment, the recess and housing can be arranged in a midsole
of the sole unit, where the sole unit also includes a removable
insole for covering the recess when the article is in use. If the
housing is arranged in such a recess, it is well protected, since
it is surrounded by sole material from all sides. The insole is
typically removable and, therefore, does not impair the direct
access to the housing of the electronic assembly for, for example,
changing the battery. In addition, a shape of the recess can
correspond to a shape of the housing for the electronic assembly.
The complementary shapes can aide in the retention of the housing
within the sole unit by providing a positive fit when the housing
is inserted, so that the housing is arranged substantially without
play inside the recess of the sole. Vibrations, which after some
time could damage an electronic assembly arranged inside the
housing, are, therefore, essentially eliminated.
[0016] Additionally, the recess can include at least one receptacle
engageable by a projection of the housing. The receptacle can be an
opening into or through the recess, or an indentation in a wall of
the recess. In one embodiment, the receptacle can include
additional structure for engaging the projection and/or the
receptacle and projection can have complementary shapes. In one
embodiment, the recess includes at least two receptacles oriented
substantially opposite each other. The recess can include at least
one elastic element to secure the housing in the recess. The
elastic element can either be formed within the sole unit proximate
the recess or be integrated into the recess. The elastic element
can be an elastic boundary for circumscribing at least a portion of
the housing to rigidly fix the housing inside the recess. As a
result, the housing is, in addition to the above-explained positive
fit, actively anchored to the recess so that almost any movement of
the housing inside the recess is eliminated. Furthermore, the
recess can include at least one projection for engaging with a
corresponding receptacle in the housing. In one embodiment, the
recess includes two projections at each of a front end and a rear
end, respectively, in a longitudinal direction of the article of
footwear. Each projection is engageable with a corresponding
receptacle in the housing. Generally, the receptacles and/or
projections of the recess can be formed in the sole unit proximate
the recess or disposed in the walls of the recess if, for example,
the recess is a separately formed tub-like structure disposed
within the sole unit.
[0017] The article of footwear can also include a removal strap
disposed at least partially within the recess to facilitate removal
of the housing from the recess. The removal strap can be arranged
within the recess such that a portion of the strap is positioned
below the housing when the housing is disposed within the recess
and an end of the strap extends over a top edge of the recess. In
one embodiment, the removal strap includes an aperture for
receiving a projection of the housing, when the housing is disposed
in the recess of the article. Further, at least a portion of the
recess can be integrated into or formed by at least a portion of a
reinforcing element of the sole. The reinforcing element can be a
support bar configured to control a rotation of a forefoot portion
relative to a rearfoot portion of the sole unit. Such a torsion
support or torsion bar is typically made from a substantially
incompressible material to achieve the desired support function and
is, therefore, particularly suitable for securely receiving the
housing for the electronic assembly. Alternatively or additionally,
the reinforcing element can be a plate for dispersing impact forces
arising on the sole or providing energy return to the wearer's foot
during a push-off phase of a step cycle. Examples of reinforcing
elements in shoe soles can be found in U.S. Pat. No. 6,199,303 and
U.S. patent application Ser. No. 09/561,584, the entire disclosures
of which are hereby incorporated by reference herein. Further,
tests showed that this arrangement leads to accurate measuring
results if an accelerometer is used. The article of footwear can
also include an attachment means for securing the article of
footwear to a wearer's foot and a mounting cover engageable with
the attachment means. The mounting cover can be configured to
receive a second housing configured for receiving an electronic
assembly. The attachment means for securing the article of footwear
onto the wearer's foot includes, for example, laces, hook and loop
type fasteners, zippers, snaps, and combinations thereof.
[0018] In another aspect, the invention relates to a housing for
receiving an electronic assembly. The housing includes a first
portion having an exterior surface and a second portion having an
exterior surface and releasably coupled to the first portion. The
exterior surfaces have a shape configured for engaging a recess
formed within a sole of an article of footwear. Such a housing is
particularly suited to be used together with a shoe having the
above described features and to securely receive an electronic
assembly. The housing may be permanently connected to the
electronic assembly or the electronic assembly can be releasably
arranged inside the housing.
[0019] In various embodiments, the housing includes at least one
projection disposed on the external surface of at least one of the
first portion and the second portion. The projection can extend
partially from both portions. The at least one projection can be
configured to engage a corresponding receptacle within the recess
or formed in the sole unit proximate the recess. In one embodiment,
the housing includes at least two projections oriented
substantially opposite each other on the housing. The at least two
projections can be configured to engage at least two corresponding
receptacles within the recess or formed in the sole unit proximate
the recess. Furthermore, the projection(s) can be made from an
elastic material to facilitate engaging the receptacle of the
recess. Additionally, the housing can include at least one
receptacle disposed in the first portion or the second portion, or
both. The at least one receptacle can be configured to receive a
corresponding projection disposed within the recess. In one
embodiment, the housing includes two receptacles disposed at each
of a front end and a rear end of the housing in a longitudinal
direction. Each receptacle can be configured to receive a
corresponding projection of the recess. The projection either
formed by the sole unit proximate the recess or extending from a
sidewall of a separately formed recess, such as the afore-mentioned
tub-like structure.
[0020] In additional embodiments, the housing includes a cover made
of an elastic material. In one embodiment, the cover may encompass
substantially the entire housing. Thus, a firm fit in the shoe's
recess is on the one hand obtained and, on the other hand, the
housing is protected if it is removed from the recess and, for
example, falls onto a hard floor. The housing can include a seal
arranged between the first portion and the second portion. In one
embodiment, the housing includes an opening defined at least
partially by at least one of the first portion and the second
portion. The opening can be configured to enable access to an
interior portion of the housing by a user. The housing can also
include a mounting cover engageable with an attachment means for
securing the article of footwear to a wearer's foot, the mounting
cover configured to releasably receive and at least partially
circumscribe the housing. The housing may also be releasably
attached in a conventional manner to any arbitrary shoe, if the
shoe does not provide a suitable recess in the shoe sole. The use
of the housing and the electronic assembly arranged therein does,
therefore, not necessarily require the use of a unique pair of
shoes. Moreover, the mounting cover makes it possible to use the
assembly additionally or alternatively for a display or the like,
being arranged on the laces and displaying data measured and/or
generated by a further assembly within the shoe.
[0021] The mounting cover can include an attachment strap extending
below the housing and configured to engage with the attachment
means of the article of footwear. In one embodiment, the mounting
cover includes at least one mounting arm extending below the
housing and below the attachment means of the article of footwear.
The mounting arm can include an end region at least partially
encompassing a top surface of the housing. In another embodiment,
the mounting cover can include at least two mounting arms extending
below the housing and below the attachment means of the article of
footwear. The mounting arms can include end regions that at least
partially encompass a top surface of the housing. In addition, the
mounting cover can include a mounting flap. The mounting flap
defining an aperture configured for receiving a projection disposed
on the housing.
[0022] Moreover, the housing can include an electronic assembly
disposed therein. The electronic assembly configured for
communicating with a user interface located outside of the housing.
In one embodiment, the housing defines an aperture configured for
passing a cable therethrough. The cable can be configured to
provide communication between the electronic assembly and the user
interface. Additionally or alternatively, the electronic assembly
can communicate with the user interface in a wireless manner.
[0023] These and other objects, along with advantages and features
of the present invention herein disclosed, will become apparent

the features of the various embodiments described herein are not
mutually exclusive and can exist in various combinations and
permutations.

DETAILED DESCRIPTION
[0038] In the following, embodiments of the invention are described
with reference to an electronic pedometer in a running shoe. The
following interprets the term "pedometer" as any electronic
assembly detecting in any manner the running movement
electronically, e.g., to determine the number of steps done, the
acceleration, the speed, or other physical values in connection
with the running movement. It is, however, to be understood that
the present invention also relates to the arrangement of other
kinds of small electronic assemblies in shoes, including, but not
limited to a shock sensor, a global positioning system, a pulse
sensor, an accelerometer, a speed sensor, and an MP3 player.
[0039] FIGS. 1A and 1B depict an electronic device, such as a
pedometer, provided inside a housing 10 having a front end 9a and a
rear end 9b arranged in a recess of a sole 3 of a shoe 1 including
an upper 6. To this end, a removable insole 2 or a so-called sock
liner is at first removed from within the upper 6 (FIG. 1A).
Subsequently, the housing 10 is arranged in a recess of the midsole
through the upper 6 (FIG. 1B). The recess for receiving the housing
10 may alternatively also be provided in a removable insole 2 or
the midsole and the insole 2 together may form a cavity for the
housing 10. In general, it is also possible to provide the recess
for releasably receiving the housing 10 in an outsole. In another
modification of the described embodiment, the electronics of the
device can be fully integrated into the removable insole of the
running shoe.
[0040] Furthermore, the electronic assembly 10 may be operated
after it has been arranged in one of the afore-mentioned sole
layers. For example, openings 4 can be arranged in the surrounding
sole layers or keys can be provided that allow the operation of
corresponding input means on the housing 10. It is also possible to
manufacture parts of the sole layers surrounding the inserted
housing 10 from a transparent material to allow for inspection of a
display on the housing 10 or to allow the transmission of a light
signal that might, for example, indicate the proper functioning of
the electronic assembly. Alternatively or additionally, infrared
light can be used to exchange signals with the electronic assembly
to, for example, send a command to the electronic assembly or
acquire data therefrom. In one embodiment, the housing 10 itself
includes a window and/or provisions for the use of operating keys
with the electronic assembly, if required, or for observing a
display.
[0041] An exemplary illustration of a recess 20 in the midsole is
shown in FIG. 2. For the sake of simplicity, the midsole material
surrounding the recess 20 is not shown. The recess 20 has
substantially the shape of a tub, wherein at least one of its inner
dimensions, i.e., its length, width, or depth corresponds
substantially to the outer dimensions of the housing 10. In one
embodiment, all of the dimensions correspond. The recess 20 may
include elastic inserts or edge sections to ensure a firm fit of
the housing 10 in the recess 20. When the housing 10 is inserted
into the recess 20, as shown in FIG. 2, there is a positive fit so
that relative movements inside the recess 20 are substantially
excluded. Furthermore, it is desirable for the top surface of the
inserted housing 10 to be substantially flat to avoid bulges in the
insole 2 and, therefore, such an arrangement of the housing 10 has
no significant influence on the wearing comfort of the shoe 1.
[0042] In one embodiment, the recess 20 can be formed within the
sole or, alternatively, the recess 20 can be a tub-like structure
integrated into the sole by, for example, injection molding the
sole around the recess 20. The recess 20 can be arranged in the
midfoot area of the shoe and, for example, integrated into a device
for supporting the arch of the foot, which is typically made from a
harder material than the surrounding sole material. In one
embodiment, an arrangement of the recess 20 in a support bar (FIG.
9) allows torsional flex of the foot, i.e., rotation of the
forefoot relative to the rearfoot. Furthermore, the recess 20 can
be located in other regions of the sole, for example the forefoot
or heel regions, and more than one recess 20 can be provided. In
one embodiment, multiple recesses 20 can be included, where the
sizes of the recesses 20 can vary to suit a particular application
or type of electronic device.
[0043] FIG. 2 discloses one possible manner in which the housing 10
may be attached to the recess 20. Specifically, receptacles 22,
such as through openings or indentations, are located in the
sidewalls 21 of the recess 20, and projections 11 extending from
the housing 10 extend into and/or through the receptacles, thereby,
attaching the housing 10 inside the recess 20. As can be seen from
FIG. 2, the sidewalls 21 include several receptacles 22 that can be
arranged in pairs on opposing sidewalls 21. The sidewalls 21 may be
the longitudinal sides and/or the lateral sides of the recess
20.
[0044] The arrows in FIG. 2 illustrate how the projections 11 are
initially inserted into the corresponding receptacle 22 of a
sidewall 21 before the housing 10 is downwardly pressed so that the
opposite projections 11 can engage the corresponding receptacles 22
of the opposite sidewall 21. In one embodiment, the sidewalls 21
and/or the projections 11 have a certain elasticity. In one
embodiment, the projections 11 have an optional outer rubber
coating 12 (FIG. 3) providing the required elasticity. The rubber
coating 12 may either be made from a continuous rubber material or
it has inner cavities (FIG. 4) filled by air or, if necessary,
specific cushioning materials, such as a gel. For an easier
handling of the housing 10, the outside of the rubber coating 12
may include one or more profile elements 7. The outer rubber
coating 12 is compliant and, thereby, aides in the insertion of the
housing 10 within the recess 20. In other words, the projections 11
(or recess 20) may bend or otherwise yield to the force required to
insert the housing 10 within the recess 20, but then return to
their original shape to hold the housing 10 within the recess
20.
[0045] The rubber coating 12 additionally protects the housing 10
and the electronic components of the device arranged therein, when
the housing 10 is removed, for example for connecting to a PC, and
unintentionally dropped. It is, therefore, also possible to provide
the housing 10 with a rubber coating that covers not only the
disclosed four projections 11, but also completely covers the
housing 10, as explained below in more detail with reference to the
alternative embodiment shown in FIG. 11. This is particularly
desirable when a mounting cover is used, as described subsequently,
such that the housing 10 is arranged on the laces without the
protection of the surrounding sole material.
[0046] In an embodiment of the invention where the electronic
device uses a shock sensor, it is desirable to anchor the housing
10 in the recess 20 without any play. Any acceleration acting on
the housing 10 and, thereby, on the device corresponds to an
acceleration of the shoe 1 and not to a relative movement between
the housing 10 and the shoe 1. This secure fit can be accomplished
by, for example, sizing the recess 20 and housing 10 such that
there is a slight interference fit therebetween. The elastic nature
of at least portions of the recess 20 can allow the edges 9 or
sidewalls 21 of the recess 20 to expand to receive the housing 10
and contract to hold the inserted housing 10.
[0047] FIG. 4B depicts an alternative arrangement of the
projections 11 and the receptacles 22 described hereinabove. As
shown in FIG. 4B, the projections 11' are located within the recess
20' and are configured to engage receptacles 22' located on the
housing 10'. In the embodiment shown, the projections 11' extend
inwardly from the sidewalls 21' of the recess 20'.
[0048] FIG. 5 shows an exploded view of one embodiment of a housing
10 in accordance with the invention. As can be seen, the
construction includes a first portion, i.e., lower half 15, a
second portion i.e., upper half 16, and an intermediate seal 17
disposed therebetween to avoid the penetration of dirt and/or
humidity. The seal 17 is desirable when the two portions 15, 16 are
releasably interconnected to allow the removal of an electronic
assembly arranged in the interior 8 of the housing 10.
Alternatively, it is also possible to permanently interconnect the
two portions 15, 16 after the initial installation of the
electronic assembly by, for example, gluing, fasteners,
high-frequency welding, or other techniques.
[0049] In the embodiment of FIG. 5, the two portions 15, 16 are
interconnected by having the integral rubber coating 12 extending
over both the upper half 11a and the lower half 11b of a lateral
projection 11 of the housing 10. Additionally or alternatively,
latches and/or screws can be used for interconnecting the upper and
the lower portion 15, 16 of the housing 10. Furthermore, in one
embodiment, the housing 10 can be formed as a single component.
[0050] As further shown in FIG. 5, the housing 10 can include an
opening 18 on its top side with a cover 19 and a seal 19a, for
example an O-ring. As a result, a battery or an accumulator can be
easily replaced, without the housing 10 having to be removed from
the recess 20. Instead of an opening, the housing 10 could also
include a charging socket so that an accumulator arranged in its
interior can be charged externally by using a cable.
[0051] FIGS. 6 to 8 illustrate an embodiment of a mounting cover 30
in accordance with the invention. The mounting cover 30 allows for
the attachment of the above-described housing 10 to the fastening
means, for example laces, of a common shoe. This arrangement can be
used where the shoe does not include the above-described recess 20
or if an additional electronic assembly, for example an MP3 player,
is to be attached to the shoe in addition the first electronic
assembly, for example a pedometer. Similar to the recess 20, the
mounting cover 30 comprises side-walls with receptacles 32 that can
be penetrated by the projections 11 of the housing 10. As a result,
the housing 10 can reliably, but releasably, be fixed to the
mounting cover 30. Also the receptacles 32, either as openings or
indentations, can be arranged in opposite pairs. The depicted
embodiment has a shape and size corresponding substantially to the
external dimensions of the housing 10 and includes four receptacles
32, similar to the above-described embodiment of the recess 20,
that are engaged by the four corresponding projections 11 of the
housing 10 (FIG. 8).
[0052] In one embodiment, the mounting cover 30 may include an
attachment strap 35 located on its lower side. The attachment strap
35 provides a removable connection to the laces (FIG. 7) or to
other attachment means for securing a shoe to a wearer's foot. The
attachment strap 35 is guided below the laces and includes an
aperture 36 located on its free end that can be releasably attached
to a front end 9a of the housing 10 (FIG. 8). To this end, a
suitable projection 14 can be arranged on the front end of the
housing 10. Other attachment means are also possible and considered
within the scope of the invention, including, for example, a
snap-fastener for securely connecting the free end of the
attachment strap 35 to the housing 10 and/or the mounting cover
30.
[0053] FIGS. 9, 10, and 11 depict an alternative embodiment of the
invention. As described above, an approximately tub-like recess 120
is again arranged in a midfoot region of a shoe sole 100, for
example, in a midsole, the inner dimensions of which correspond
substantially to the outer dimensions of a corresponding housing
110. As shown in FIG. 11, the housing 110 has an approximately
turtle-like shape. In the embodiment shown in FIG. 9, the shoe sole
100 includes an optional torsion bar 127 disposed therein. The
recess 120 either passing through or at least partially defined by
the torsion bar 127.
[0054] In a lateral region (e.g., at the front end of the recess
120) that is marked in FIG. 9 by a dashed circle, there is a slit
111 into which a removal strap 130 can be mounted by, for example,
gluing. When the housing 110 is inserted into the recess 120, as
shown in FIG. 9, the removal strap 130 lies flat below the housing
110. Only a boundary region 131, optionally including a
reinforcement 132 to facilitate gripping, protrudes from the recess
120. Since, however, the boundary region 131 and the reinforcement
132 are preferably arranged below an insole, i.e., a sock liner,
the comfort of wearing the shoe is unimpaired.
[0055] The removal strap 130 facilitates removal of the housing 110
of the electronic assembly from the shoe sole 100. Despite a firm
fit in the recess 120, as obtained by, for example, covering the
housing 110 with an elastic layer (e.g., rubber) the housing 110
may be removed from the recess 120 of the sole 100 simply by
pulling the removal strap 130. Neither a particular force nor
specific tools are required. In one embodiment, the removal strap
is substantially flexible to conform to the shape of the housing
110 and recess 120.
[0056] FIG. 10 shows one embodiment of the removal strap 130. The
removal strap 130 has a substantially elongate shape and includes
an optional aperture 133 disposed therein. A projection 117 of the
housing 110 (FIG. 11) can pass through the aperture 133 and engage
the recess 120 in the mounted position of the housing 110. Thus,
the removal strap 130 is correctly aligned to facilitate the later
removal of the housing 110 in the manner explained above.
[0057] FIG. 11 depicts an embodiment of the housing 110 that
includes a plurality of optional indentations 115 that can be
arranged in pairs at the front and rear ends of the housing 110.
Corresponding projections 105 arranged in the interior 121 of the
recess 120 can engage these indentations 115, for example in pairs
at the front and rear ends of the recess 120. Thus, the housing 110
is firmly positioned in the recess 120. Alternatively, embodiments
of the invention are possible where the housing 110 is only
arranged in an approximately correspondingly shaped recess 120 of
the shoe sole, without any further measures.
[0058] In addition, to improve handling of the housing and the
electronic assembly with its sensitive circuits arranged therein,
the rubber layer can have regions 116 with groove-like indentations
107 disposed thereon to promote a secure grip. The embodiment of
FIG. 11 shows three such regions 116 located, for example, at the
front end of the housing 110 besides the indentations 115 and at
the rear end of the housing 110 between the two rear indentations,
respectively. Measures other than the interaction of the
afore-mentioned projections and indentations are possible to ensure
a secure mounting of the housing 110 in the recess 120. For
example, the housing 110 may be fixed in a certain position by a
magnet, or the recess 120 may include a closable cover that
additionally fixes the removable housing 110 therein.
[0059] An alternative embodiment of a mounting cover 150 that can
used with the embodiment of the housing 110 of FIG. 11, is shown in
FIG. 12. The mounting cover 150 will only encompass the housing 110
partially. The mounting cover 150 has arms 151 configured to extend
beneath the laces, or other attachment means of the shoe, and end
in hook-like, upwardly bent end regions 152, thereby forming a
receptacle for receiving the housing 110. The housing 110 is
clipped into the thus-formed receptacle from the top so that the
hook-like end regions 152 encompass the housing at its top surface.
Instead of the four arms 151 shown in FIG. 12, other numbers of
arms are possible, e.g., three arms or only two arms of wider
dimensions, encompassing the housing 110 at the top and bottom end
or at the sides. Further, a mounting flap 155 may be included on
the mounting cover 150, as shown in FIG. 12, extending over the
projection 117 and thus anchoring the housing 110 securely in the
mounting cover 150 in addition to the clipping of the housing 110
within the hook-like end regions 152.
[0060] FIG. 13 discloses an optional manner of controlling the
electronic assembly arranged inside the sole or on the instep, in
addition to or alternatively to the above described input
possibilities through the sole. Using a wireless link, the
electronic assembly arranged in the housing 10 inside the shoe sole
communicates with a receiving unit 50 carried, for example, on the
wrist. To this end, a wireless transmission standard such as
Bluetooth.RTM. or the like may be used. Since the actual
electronics are arranged inside the housing in the shoe sole, the
receiving unit 50 at the wrist (or at any other position) can be
very light-weight, small and, for example, be integrated into a
watch or garment. In addition, an arrangement in a strap similar to
an electronic assembly for measuring the pulse is also
possible.
[0061] The wireless transmission between the unit 50 and the
electronic assembly inside or at the shoe sole may be
bi-directional, so that the electronic assembly can be controlled
using the unit 50. Instead of a wireless transmission, a thin cable
may be used which is guided through the housing 10 to the outside
and connected to a control and/or display unit outside the shoe
sole.
[0062] Moreover, the electronic assembly may be electrically
connected to a plurality of additional sensors that are not
arranged in the housing itself, but at other locations in the shoe,
for example, in the sole region, in the shoe upper, in the forefoot
region, in the rearfoot region, etc. Since not all possible
connections to the electronic assembly are required for every shoe,
it is also possible that only a portion of a plurality of provided
electrical connections are actually connected. This is in
particular sensible if an offerer distributes an electronic
assembly that is able to detect a large number of different
parameters (speed, acceleration, GPS position, deformation of the
shoe, pulse rate, etc.) during running, which are provided by a
complex and thus expensive shoe with the entirety of all possible
sensors. Due to its modular character, the device can, however,
also be used with a simpler and less expensive shoe in which only a
portion of the sensors is actually provided.
[0063] The various components, for example the tub-like structure,
can be manufactured as a single plastic part by injection molding
or extrusion. Both methods lead to very low manufacturing costs, a
low weight, easy adaptation to different sizes, for example adult
versus children shoes, by using correspondingly adapted molds for
injection molding. In some embodiments, the components can be
manufactured by multi-component injection molding more than one
plastic material. For example, a harder plastic material can be
used for the housing 10 and particularly soft and elastic plastic
material can be used for the projections 11. The multi-component
injection molding may be performed simultaneously using one or more
nozzles or sequentially. Alternatively, the plastic material can be
injected around separately pre-manufactured components.
[0064] Suitable plastic materials include: thermoplastic
polyurethanes (TPU); polypropylene (PP); ethylene vinyl acetate
(EVA); thermoplastic polyether block amides, such as the Pebax.RTM.
brand sold by Elf Atochem; thermoplastic polyester elastomers, such
as the Hytrel.RTM. brand sold by DuPont; thermoplastic elastomers,
such as the Santoprene.RTM. brand sold by Advanced Elastomer
Systems, L.P.; thermoplastic olefin; nylons, such as nylon 12,
which may include 10 to 30 percent or more glass fiber
reinforcement; silicones; polyethylenes; acetal; and equivalent
materials. Reinforcement, if used, may be by inclusion of glass or
carbon graphite fibers or para-aramid fibers, such as the
Kevlar.RTM. brand sold by DuPont, or other similar method. Also,
the polymeric materials may be used in combination with other
materials, for example natural or synthetic rubber. Other suitable
materials will be apparent to those skilled in the art.
[0065] Moreover, the material selection, as well as the size and
shape of the housing 10 and recess 20 can vary to suit a particular
application and can easily be optimized using a
finite-element-analysis. For example, the housing 10 can have
essentially any shape, such as polygonal, arcuate, or combinations
thereof, and be sized based, at least in part, on the type of
electronic assembly housed therein and the specific location the
housing will be mounted or inserted into.
[0066] Having described certain embodiments of the invention, it
will be apparent to those of ordinary skill in the art that other
embodiments incorporating the concepts disclosed herein may be used
without departing from the spirit and scope of the invention. The
described embodiments are to be considered in all respects as only
illustrative and not restrictive.
